Is Moss Bad For My Roof

In this post, I will be answering your question of is moss bad for my roof so stay tuned:

Moss is a flowerless plant that grows vigorously in shady and moist areas. They are found everywhere in the world, except in saltwater. They are generally 0.3 to 10 cm tall. However, some of its species are taller. They are so small in size that they are generally confused with fungus. However, they are actually plants.

Many homeowners see moss as a headache as it can damage the new roof and also removing moss can be a pain.

Some people think that moss is bad for your roof because they believe it will grow indefinitely. There are a few good reasons to remove moss from your roof, but this is not one of them.

Moss can be considered a risk if you don’t have the time or resources to properly maintain the roof. Moss on roofs can cause leaks and really damage your shingles over time. It’s better than green algae under a roof, though, which could actually eat away at shingles and create all sorts of problems! It’s also better than dirt accumulating under your roof, which would eventually lead to poor drainage (causing mold) as well as pest infestations.

The best thing about moss is that it doesn’t cast shade like other grasses and plants. This means if you choose to grow it, it won’t block out the sun as other plants can. What this also means is that your new roof needs to be shingled with a light color material in order for moss to survive on it.

There are many misconceptions about moss. So, in this article, we aim to clear those misconceptions and discuss whether moss is beneficial or harmful for your roof and whether you should remove the moss or not.

Let’s delve further and find out!

Is Moss Bad For My Roof?

Mosses are widely found in roofs of almost all countries in Europe and the USA. There would be hardly a roof in the aforementioned areas with no moss. Honestly, moss in a controlled proportion looks attractive and makes your home look charming. So is moss really bad for your roof and whether you should kill the moss through pressure washing or a professional moss removal service to protect your roof?

Well, the simple answer is yes. Let’s discuss how it is harmful to your roof.

As mentioned earlier, moss grows in shady and moisture areas. If your house is situated in one of those areas where the atmosphere is generally favorable for its growth, it is very likely to grow on your roof. Of course, no homeowner wants to see his roof covered with moss or likes to see moss covered roof.

Here is how moss can cause damage to your roof:

Moss Growth Causes Leaks

The most obvious drawback of mosses on your roof is that they may cause leaks. When moss grows on your roof, it pushes underneath tiles, shingles, and other roof materials. As a result, tiles and shingles are pushed up and uprooted from the roof surface. All of this results in immense damage, often in the form of holes and leakages.

To make things worse, when you try to eliminate dead moss from your roof, tiles, and shingles will be pushed back in a weird way leading to further structural degradation. To put things briefly, they can be a recipe for disaster for a roof.

Roof Moss Puts More Weight on Your Roof

Another reason why you should never let mosses grow on your roof is that it puts a lot of unwanted weight on your roof. Mosses retain a big amount of water. It goes without saying that if there is a lot of moss on your roof, it will put extra hundreds of pounds of weight on your roof. Your roof is not designed to support that much unwanted extra weight.

Hence, it’s not good for your roof’s health and the life of the roof reduces.

Moss From Your Roof Reduces Your Home’s Worth

Well, if you are looking to sell your house, know that the mosses on your roof can be a big reason to worry. The moss on your roof will give an impression that you haven’t taken care of your house. It can offend many potential buyers and ultimately, your house’s worth will be reduced. So it can cost you thousands of dollars. 

It’s a Safety Hazard

Mosses have moisture which makes them slippery. There will be less friction which makes it difficult for your feet to make a proper grip on the floor. So there are chances that you may fall and get injured if you try to walk on a moss-covered roof. 

It is a Home to Insects

It’s no secret that moss is home to many insects. Bugs and rodents will be attracted to your home because of this. Needless to say that insects can be annoying and dealing with them can be a frustrating experience.

It May Get You Fined

In some countries, it’s not allowed to let moss grow on your roof. So if you have moss on your roof, reach out to your local housing authority to confirm whether it’s legal or not. They may find you and ask you to get rid of it as soon as possible.

How to Get Rid of Moss on Your Roof?

Now that we have discussed the ill effects of moss on your roof, now let’s discuss how you can eliminate it. This DIY approach is easy to follow and you will not need professional services also.

Many homeowners try to eliminate the moss from growing on their own from their roofing. Bear in mind that it can lead to unpleasant consequences if you don’t have the right knowledge. It’s not as simple as it may seem and you may end up damaging your roof even more. So, it’s recommended to ask a home improvement company to help you out on this. If you somehow try to do it by yourself, make sure to take all safety measures before getting onto it. 

To remove the moss and algae or stop moss growth, use a cleaning solution that is meant to eliminate moss. Some people don’t buy the solution and use dish soap instead to kill moss.

Be mindful that any detergent (used in a spray bottle) or soap is not as effective as a cleaning solution for removing moss. So rather than saving a few bucks, buy a roof cleaning solution. 

Rainy days are an ideal time to eliminate mosses. This is because, on normal days, the spray will evaporate in no time. So on a dry day, you’d have a hard time trying to eliminate mosses. 

If you want to remove mosses on your own, another thing to bear in mind is to never pressure wash your roof. Especially if there are shingles on your roof as pressure wash can damage them. The water may be pushed even further and ultimately, your roof’s health will be affected. To add to that, it won’t even eliminate mosses completely. 

To prevent moss from growing on your roof, make sure there is a minimum shady area. If there is a tree that causes shade on your roof, prune some of its branches so that there is no shade on your roof. Sunlight is your friend and helps you get rid of mosses naturally. Furthermore, keep inspecting your roof every now and then to make sure there is no moss growing in there. 

Is it necessary to remove moss from a roof?
